See the stunning image James Webb took to celebrate its first birthday

Today marks the one-year anniversary of the first images shared from the James Webb Space Telescope, and to celebrate this milestone NASA has shared yet another gorgeous image of space captured by Webb.

The new image shows a star system called Rho Ophiuchi; a busy region where new stars are being born amide swirls of dust and gas. Located just 390 light-years away, Webb was able to capture the region in stunning detail using its NIRCam instrument.

The first anniversary image from the NASA/ESA/CSA James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture. The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth. It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. Some stars display the telltale shadow of a circumstellar disc, the makings of future planetary systems.

The region is made up of multiple star systems, with large amounts of gas such as molecular hydrogen, which is shown in red. As stars are formed in the swirl of dust and gas, they give off light and radiation in a phenomenon called stellar wind. This wind blows away material from around the young stars, both preventing other stars from being formed too nearby and also sculpting the dust and gas into distinctive shapes.

Particularly bright bursts of energy are given off by young stars which form jets, throwing out material from both poles and creating the red streaks of molecular hydrogen at the top and right of the image.

Stars are the only objects being formed in this image though. Several of the stars also have shadows around them which indicate the presence of protoplanetary disks. These disks of dust and gas form around a star, gradually growing over time due to the star’s gravity. Clumps start to form within the disk, beginning with tiny particles and building up to become larger and larger over time. Eventually, the clumps can gain enough mass to form a solid core, creating the basis for a new planet. So the systems in this image include not only new stars but also forming planets as well.

There are a total of around 50 young stars shown in the image, each of them similar to our sun. The clouds of dust around the stars are warmed by their radiation, with bright infrared sources which Webb is able to pick up on thanks to its infrared instruments.

One galaxy, two views: see a comparison of images from Hubble and Webb
The peculiar galaxy NGC 3256 takes centre stage in this image from the NASA/ESA Hubble Space Telescope. This distorted galaxy is the wreckage of a head-on collision between two spiral galaxies which likely occurred 500 million years ago, and it is studded with clumps of young stars which were formed as gas and dust from the two galaxies collided.

It might not seem obvious why astronomers need multiple different powerful space telescopes. Surely a more powerful telescope is better than a less powerful one? So why are there multiple different telescopes in orbit, either around Earth or around the sun?

The answer is to do with two main factors. One is the telescope's field of view, meaning how much of the sky it looks at. Some telescopes are useful for looking at large areas of the sky in less detail, working as survey telescopes to identify objects for further research or to look at the universe on a large scale -- like the recently launched Euclid mission. While others, like the Hubble Space Telescope, look at small areas of the sky in great detail, which is useful for studying particular objects.

James Webb spots the most distant active supermassive black hole ever discovered
Crop of Webb's CEERS Survey image.

As well as observing specific objects like distant galaxies and planets here in our solar system, the James Webb Space Telescope is also being used to perform wide-scale surveys of parts of the sky. These surveys observe large chunks of the sky to identify important targets like very distant, very early galaxies, as well as observe intriguing objects like black holes. And one such survey has recently identified the most distant active supermassive black hole seen so far.

While a typical black hole might have a mass up to around 10 times that of the sun, supermassive black holes are much more massive, with a mass that can be millions or even billions of times the mass of the sun. These monsters are found at the heart of galaxies and are thought to play important roles in the formation and merging of galaxies.

Saturn as you’ve never seen it before, captured by Webb telescope
Saturn captured by the James Webb Space Telescope

NASA has shared a gorgeous image of Saturn captured recently by the James Webb Space Telescope (JWST).

Webb’s first near-infrared observations of the second largest planet in our solar system also show several of Saturn’s moons: Dione, Enceladus, and Tethys.
